perfect for partial shade. I love coleus! It is considered a tender perennial & can take either sun or shade (but read grower's tag to see what that cultivator prefers). Keep soil moist & pinch flowers so plant stays bushy & reblooms.
Just need the perfect copy for USA Zone 10 - Purple Flowering Groundcover - Campanula Portenschlagiana - a plant that grows in less-than-ideal conditions and has long-lasting foliage. Plant care info is on the post - via Northern Shade
